Area code 858 serves the northern portion of the City of San Diego along with the adjacent cities of Del Mar, Poway and Solana Beach and a small portion of the City of Encinitas, as the California Public Utilities Commission puts it.
Its rate centers are Del Mar, La Jolla, Poway, Rancho Bernardo, Rancho Penasquitos, Rancho Santa Fe, Linda Vista and Mira Mesa. Since 2018 the line with 619 is gone, so either code can be given to a number anywhere in San Diego, Chula Vista or El Cajon.
